Chrome OS version 64 has made its way to stable channel, which means it's hitting your device very, very soon if it hasn't yet. It'll add a handful of new features and improvements, including a screenshot shortcut if you have a Chromebook with a 360-degree hinge like the Acer Spin. You only have to press the power and the volume down buttons at the same time, like what you'd do on an Android phone. It also adds a flag to make Split View easier to activate and gives Android apps the ability to run in the background. In addition, the update improves your lockscreen's performance, presumably making it faster, and finally enables the use of VPN for apps downloaded from Google Play.
